Until now, drag and drop for web applications has, for the most part, been limited to specialized JavaScript frameworks such as Script.aculo.us and Rico. No more. With the advent of GWT, we have drag-and-drop capabilities in a Java-based web application framework. Although Google Web Toolkit (GWT) does not explicitly support drag and drop (drag and drop is an anticipated feature in the future), it provides us with all the necessary ingredients to make our own drag-and-drop module. In this solution, we explore drag-and-drop implementation with GWT. We implement drag and drop in a module of its own so that you can easily incorporate drag and drop into your applications.

Today, we are going to take a look at adding drag-and-drop to our GWT applications. I’ve seen quite a few solutions for adding drag-and-drop, including a few tutorials that show how roll your own solution. But why reinvent the wheel when there is a perfectly good drag and drop library like gwt-dnd ?

Now that I have GWTDesigner by Instantiations, I am well armed to continue development in GWT.
I am building an agile project planning tool that makes heavy use of drag and drop to facilitate planning of user stories into iterations as recommended by the eXtreme Programming Planning Game.
